با سلام
می خواهم که یک متن را از داخل یک سرور برای مثال با آدرس 192.168.0.1 به یک کلاینت به آدرس 192.168.0.2 بفرستم با پورت فرضی 8080 ،چگونه باید عمل کنم.
با تشکر

این کد دارای دو بخش Client و Server است.

این کد بخش Server :



using System;
using System.Windows.Forms;
using System.Net.Sockets;
using System.IO;

namespace TCPSocketServer
{
/// <summary>
/// Summary description for TCPSockServer.
/// </summary>
public class Server : Form
{
//////////////////////////////////////////////////////////////////////////////
///Variables & Properties

public Server()
{
//create StartServer button set its properties & event handlers
this.btnStartServer = new Button();
this.btnStartServer.Text = "Start Server";
this.btnStartServer.Click +=
new System.EventHandler(this.btnStartServer_Click);

//add controls to form
this.Controls.Add(this.btnStartServer);
}

//////////////////////////////////////////////////////////////////////////////

private bool StartServer()
{

this.btnStartServer.Enabled = false;
//block tcplistener to accept incoming connection
Socket serverSocket = tcpServerListener.AcceptSocket();

try
{

{
Console.WriteLine("Client connected");
//open network stream on accepted socket
NetworkStream serverSockStream =
new NetworkStream(serverSocket);
serverStreamWriter =
new StreamWriter(serverSockStream);
serverStreamReader =
new StreamReader(serverSockStream);
}
}
catch(Exception e)
{
Console.WriteLine(e.StackTrace);
return false;
}

return true;
}

//////////////////////////////////////////////////////////////////////////////

//////////////////////////////////////////////////////////////////////////////
private void btnStartServer_Click(object sender,System.EventArgs e)
{
//start server

}


این کد بخش Client است:

{
try

}
